Creating full detector simulations
To create full simulations, you will need to convert ProMC files to LCIO files. This is described in converting_to_lcio

How to make changes in compact.xml
If you want to make changes in the detector design, edit “compact.xml”, and then run the converters:
JAVA_OPTS="-Xms2048m -Xmx2048m" GCONVERTER=lcsim/detector-framework/target/lcsim-detector-framework-3.1.6-SNAPSHOT-bin.jar GEOM="mydetector" # name of your detector java $JAVA_OPTS -jar $GCONVERTER -o lcdd compact.xml $GEOM.lcdd slic -g ${GEOM}.lcdd -G ${GEOM}.gdml echo "heprep compact.xml.." java $JAVA_OPTS -jar $GCONVERTER -o heprep compact.xml $GEOM.heprep echo "pandora compact.xml.." java $JAVA_OPTS -jar $GCONVERTER -o pandora compact.xml $GEOM.pandora java $JAVA_OPTS -jar $GCONVERTER -o html compact.xml ${GEOM}.html
where “${GEOM}” is the name of the detector geometry. Next, check that you do not have overlapping volumes. Run ROOT with the commands:
TGeoManager::Import("mydetector.gdml"); gGeoManager->ViewLeaves(true); gGeoManager->ls("All"); gGeoManager->CheckOverlaps(0.1); //0.1 tolerance or better! gGeoManager->PrintOverlaps(); gGeoManager->GetTopVolume()->Draw("ogl");
If you see that some volumes overlap, come back to “compact.xml” and make corrections.

Pandora PFA
All information required by Pandora algorithm is stored in the file with the extension “.pandora”. This file is created using GeoConvertor, which reads CalorimeterCalibration.properties file. In particular, it reads:
- mipEnergy
- mipSigma
- mipCut
- timeCut
The sampling fractions are taken from the detector directory called “SamplingFractions”. Here files look as this:
BeamCal.properties* EcalBarrel.properties* EcalEndcap.properties* HcalBarrel.properties* HcalEndcap.properties* LumiCal.properties* MuonBarrel.properties* MuonEndcap.properties* README*
Look at the file:
lcsim/detector-framework/src/main/java/org/lcsim/geometry/compact/converter/pandora/Main.java
